[Intel-gfx] [PATCH v2 2/3] glamor: turn on glamor.

[Zhigang Gong]

Add glamor's initialization to the uxa's control path.
At preInit stage, it creates and initialize EGL display
context for glamor. At the screenInit stage, it initialize
glamor's internal data structures and shaders.

And this commit enables textured pixmap also. Each pixmap
which has a valid BO can get a cooresponding texture.

After this commit. It's ready to do rendering through
glamor's rendering functions.
